The novel, which landed on multiple "Best of" year-end lists, is set in Shaker Heights, Ohio, a picturesque suburbia upended by the arrival of a rule-averse artist and her daughter. It traces the turbulent events following the adoption of a Chinese-American baby, which divides Shaker's wealthy community.

Both Witherspoon and Washington, best known for her Emmy-nominated turn as Scandal's Olivia Pope, are set to co-star and executive produce the project. Liz Tigelaar (Casual) will serve as showrunner and also pen the script. Ng will produce.

The series follows a spate of projects from Witherspoon's Hello Sunshine banner, including Wild, Gone Girl, and Big Little Lies. She's next set to lead an as-yet-untitled morning show drama with Jennifer Aniston, as well as executive produce Apple's Are You Sleeping, starring Octavia Spencer. She'll also appear in Big Little Lies' forthcoming second season, though a premiere date has not yet been announced.

Washington, meanwhile, is poised to executive produce ABC comedy Man of the Housestarring Alyson Hannigan (How I Met Your Mother). Her previous producing credits include HBO's acclaimed TV movie Confirmation and Facebook Watch series Five Points. Scandal's seventh and final season wraps April 5.
